Phoenix - redirects in router file
It would be nice to be able to define a redirect from one route to another from the router.ex file. E.g.:
redirect "/", UserController, :list
get "/users", UserController, :list
This is typically needed when you have a URL that you want the user to be able to type but that should be redirected to a more specific URL.
Ofc I can code an action and a redirect myself, but such a helper would avoid me to add that code that could be explicitly defined in the router; you can then quickly see that there is a redirect along with the other routes, without inspecting the controller’s code. I think such redirects without any logic belongs there.
What do you think about that idea?

The redirect library addresses this shortcoming by providing with a redirect/3 macro, allowing to redirect a request from one path to another in the router.exfile:
redirect "/", "/users", :permanent # 301 redirect
redirect "/", "/users", :temporary # 302 redirect

We ran into this on the project I’m working on. We found this blog post to be a pretty good way to do this: How to Redirect from the Phoenix Router | Viget
We ended up with a plug that lets us do this:
get "/", Redirect, to: "/datasets"
You can see our implementation here: smartcitiesdata/apps/andi/lib/andi_web/plugs/redirect.ex at master · UrbanOS-Public/smartcitiesdata · GitHub

It looks like there is a plug_redirect package in Hex that does adds a redirect keyword. Their Readme suggests using it as its own Plug in your endpoint, but at a quick glance I don’t see any reason you couldn’t use it in a Phoenix router

I think this is a good idea, if a little niche. although you’d want to implement it as redirect "/", "/users" because redirect "/", UserController, :list is ambiguous. Multiple paths can route to the same controller action.

Phoenix.Controller.redirect/2 is a plug, and the generated router for phoenix has it imported by default. Together with forward you should be able to use it already without the need for additional code.
